BEST MODE FOR CARRYING OUT THE INVENTION A bottom adjusting operation control system for a bed or the like according to the present invention will be described below with reference to the accompanying drawings showing one embodiment. The bed apparatus 1 is shown in FIG. 1, and this bed apparatus 1 has a bottom 3 arranged on a bed frame 2 and a back bottom 3 corresponding to the back.
a, a knee bottom 3b extending from the waist to the knee, and a foot bottom 3c corresponding to the foot, although not shown.
While the back raising link, which is a back raising mechanism, is brought into contact with the back surface of the back bottom 3a, the knee raising link, which is a knee raising mechanism, is provided on the back surface of the knee bottom 3b in order to undulate the knee bottom 3b and the foot bottom 3c. The back raising link and the knee raising link are respectively connected to driving means (described later) to perform back raising and knee raising. That is, the back raising mechanism of the back bottom 3a and the knee raising mechanism of the knee bottom 3b of the bed apparatus 1 are operated by the bottom adjustment operation control system 4 to raise the back, raise the knee, and further lower the knee and raise the knee. Is configured to do.

The bottom adjusting operation control system 4 will be described. That is, the bottom adjusting operation control system 4 is controlled by a control box (not shown) arranged on the bed frame 2 by an operation switch (described later) arranged on the operation panel 6 for operation command provided on the outer surface of the footboard 5. An operation command signal is given to the mounted controller 7, and the controller 7 supplies controlled operation power to the motors 8a and 8b which are drive sources in the back raising mechanism and the knee raising mechanism to drive the motors 8a and 8b. While starting, the position information of each bottom is obtained from the operation detecting means (not shown) of these motors 8a and 8b. Further, the controller 7 of the bottom adjusting operation control system 4 is equipped with a storage means 9 for storing an interlocking operation pattern of the bottom 3 described later.

Next, the operation panel 6 laid on the outer surface of the footboard 5 will be described. That is, FIG.
As shown in FIG. 3, the operation panel 6 has an operation switch for performing a back-raising / lowering operation, a knee-raising / lowering operation, and a back-raising / lowering knee-raising / lowering operation, that is, an arm raising switch Sw1, an arm lowering switch Sw2, The raising switch Sw3, the raising switch Sw4, the back raising knee raising interlocking switch Sw5, and the back lowering knee lowering interlocking switch Sw6 are provided. The operation panel 6 has, for example, FIG.
In order to set the bottom interlocking motion pattern as shown in Fig. 3, the back raising motion start time of the back bottom 3a and the knee bottom 3b are set.
The time setting switch St for setting the difference (t) from the knee raising operation start time and the angle setting switch Sa for setting the knee raising angle a are provided. These time setting switches St
By setting the time (t) and the knee-raising angle a by the angle setting switch Sa, they are stored in the storage means 9 in the controller 7, and the newly set motion pattern is based on the stored data. As a result, the back bottom 3a and the knee bottom 3b are interlocked.

Further, the following control procedure is set in the controller 7. (1) Knee raising operation (motor for knee raising is turned on) by operating the switch for raising the back. Then, after t hours, the back raising operation (back raising motor ON). When the knee raising angle a reaches the set angle, the knee raising is stopped (the knee raising motor is turned off), and the knee is lowered (the knee raising motor is turned on reversely). Note that t is set by the time setting switch St, and the knee raising angle a is set by the angle setting switch Sa. (2) Knee raising operation (knee raising motor O by switch operation related to Gatch (back raising operation and knee raising operation)
N). Then, after t time, the back raising operation (back raising motor O
N). When the knee raising angle a reaches the set angle, the knee raising is stopped (the knee raising motor is turned off). The back raising angle of the back bottom 3a is set so that the angle with the knee bottom 3b does not fall below 90 °, for example. Also,
Since the back-raising speed and the knee-raising speed have a constant speed in a state where the electric power to the motor is constant, the knee-raising angle a can be set by converting the knee-raising angle a for a predetermined time T based on this.

The motors 8a and 8b are provided with appropriate rotation amount detecting means (not shown) for grasping, for example, the current state of the bottom, that is, position information from the rotation amount of the motor. The detection signal from the rotation amount detecting means is
The position information is provided to the controller 7 and further provided to the operation panel 6 to be displayed on, for example, a display unit (LED or the like) so that the operator can recognize it as bottom position information.

According to the bottom adjusting operation control system 4 described above, when the back raising operation of the back bottom 3a is performed, the operation is performed in the bottom interlocking operation pattern that accompanies the operation of the knee bottom 3b. It is possible to perform the back-raising adjustment that is small and suppresses the feeling of pressure and does not burden the user. At this time, the knee-raising angle a at which the user feels a feeling of pressure is different, and the weight is different depending on the user, so that the loads on the motors 8a and 8b and the mechanism are changed, so that the back-raising speed and the knee-raising speed are changed. Therefore, on the operation panel 6, the time setting switch St for setting the difference (t) between the back raising operation start time of the back bottom 3a and the knee raising operation start time of the knee bottom 3b and the knee raising angle a (time T) are set. It is effective to reset the time (t) and the knee raising angle a by the angle setting switch Sa to be set, and to perform the back raising operation by the new bottom interlocking operation pattern stored in the storage means 9. .

For example, when the bottom 3 is flat, the warm-up switch Sw1 on the operation panel 6 is operated,
When an operation command is input to perform the back raising operation, the operation power is first supplied to the motor 8b in the direct drive mechanism of the knee raising mechanism, the knee raising link is displaced, and the knee bottom 3b is inclined. Then, after t time, the back raising motor is turned on to supply the operating power to the motor 8a in the linear drive mechanism of the back raising mechanism, the back raising link is displaced, and the back bottom 3a is inclined. Then, the knee raising angle a of the knee bottom 3b
When the angle reaches the set angle, the energization to the knee raising motor 8b is turned off, and then the knee raising motor reverse rotation is turned on. This time, the knee raising motor 8b is supplied with electric power to start the reverse rotation. The knee bottom 3b can be lowered.

In the bottom adjusting operation control system 4 according to the present invention, the bottom interlocking operation pattern can be set even during the Gatch operation to suppress the displacement of the body and the operation with less feeling of pressure is possible. In this case as well, the knee-raising angle a at which the user feels a feeling of pressure varies, so the operation panel 6
Angle setting switch Sa for adjusting the knee raising angle a in
Set the knee lift angle in advance. Further, the difference (t) between the back bottom motion start time and the knee bottom motion start time is set by the time setting switch St. The maximum back raising angle of the back bottom 3a is the knee bottom 3b.
Is restricted due to the relationship with the knee raising angle a (for example, 90 ° or more).

When a back raising knee raising interlock switch Sw5 on the operation panel 6 is operated and an operation command is input to perform a gatch operation, first, operating power is supplied to the motor 8b in the direct drive mechanism of the knee raising mechanism to move the knee. The lifting link is displaced, and the knee bottom 3b is inclined. Then, after t time, operating power is supplied to the motor 8a in the direct drive mechanism of the back raising mechanism by the back raising motor ON, the back raising link is displaced, and the back bottom 3a is inclined. Next, when a predetermined time (T) has elapsed when the knee bottom 3b reaches the set angle a,
Power to the knee raising motor is turned off, and the knee bottom 3b is turned on.
Stops and holds its tilted position (dotted line in FIG. 3).
The back bottom 3a forms an angle of 90 degrees with the knee bottom 3b.
Can be tilted to an angle that is not narrower than °.
